| 摘要: |
| 变电站数字化、智能化为站域信息共享提供了技术保障，因此开发了一种新型数字化集成保护控制（DIPC）系统。系统主要由设备层智能终端（IT）、合并单元（MU）和系统层多功能保护控制器（MPCU）三大核心部分构成，分别给出了它们的硬件架构和软件设计方案。该系统基于IEC61850标准，采用两级相量计算和保护起动判据，提高了保护的快速性和可靠性。测试结果表明，该系统可对故障作出快速、可靠的反应，其集成通信和运算能力满足保护跳闸的要求。 |

| Abstract: |
| Since the digitization and intelligentization of substation technically supports the substation-wide information sharing，a digital integrated protection and control system is thus developed，which consists of three kernels：IT（Intelligent Terminal） at equipment layer，ＭＵ（Merging Unit），and ＭＰＣＵ（Multifunctional Protection and Control Unit） at system layer. Their hardware structure and software design scheme are given. Based on IEC61850 standard，the developed system adopts two-step phasor calculation and two-step protection startup criterion to improve the rapidity and reliability of relay protection. Test results show that，it responses to fault rapidly and reliably，and its capability of centralized communication and calculation satisfies the requirements of protective trip. |
